The Responsive Data Table extension attempts to solve a common problem with HTML tables: they do not adapt very well on smaller screens.
This extension supports 3 methods to optimize the data for smaller screens.

Data can be loaded either from your local computer (CSV or MS Access) or fetched from the server (CSV or MySQL).

The demo version can be downloaded via the Extension Manager (Menu->Tools->Extension Manager->Available).
Note that this is a commercial extension, it is not free! The demo version is fully functionality, however the properties will not be saved.
